T 0 all whom it Tit/Ly con/eerie.-

Be it known that 1, CHARLES E. LOMBARD, a citizen of the United States,residing at East Wilton, in the county of Franklin and State of Maine,have invented certain new and useful Improvements in Spinning andTwisting Machines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use same,reference being had to l the accompanying drawings, and to the letl tersand figures of reference marked thereon, which form a part of thisspecification. l

This invention relates to new and useful l improvements in apparatus forspinning and twisting yarn, and comprises various details ofconstruction and combinations and arrangements of parts which will behereinafter fully described and then specifically defined I in theappended claims.

I illustrate my invention in the accompanying drawings in which:- v

Figure 1 is a side elevation of my twisting and spinning apparatus. Fig.2 is a vertical 1 sectional view through the bobbin and rotatableshafts. Fig. 3 is a detail view of a camactuated adjusting screw, andFig. 4 is an edge view of the construction shown in Fig. 3.

Reference now being had to the details of the drawings by letter, Adesignates a frame having standards A in which a shaft B is journaled insuitable bearings having a bobbin 0 fixed to rotate therewith.

D designates rollers between which the yarn D is fed, said rollers beingoperated by any suitable power mechanism.

Loosely mounted upon the shaft B are the grooved pulleys E which areconnected together by means of the rods E. Fixed to one end of a rod Eis a hook F over which the strands of yarn to be twisted are adapted topass. Corresponding ends of the rods E are fixed to a ring G mountedloosely upon the shaft.

H designates a graduated pulley which is fixed to the shaft B, and Idesignates a hollow shaft loosely journaled upon the shaft B and towhich the pulleys E are fixed.

K designates a shell which is swiveled to the shaft I and is held inposition by means of the collars K, one upon either side thereof andwhich are fixed to the shaft 1.

N designates a shaft mounted in bearings N upon said frame and has anangle lever O fixed thereto, one arm of which is pivotally connected toa link ference of said cam.

Q which in turn is pivoted to the shell K by means of a pm Q. The otherarm of the angle lever is pivotally connected to a plunger P by means ofa pivot pin P, said plunger having a longitudinally slotted portion P tothe lower end of which is pivotally connected a nut J having a threadedaperture therein to receive the screw J. The upper end of said screw hasswiveled thereto a collar J held in place by means of a nut J 1tdesignates a shaft having a heartshaped i cam it fixed thereto, saidshaft it being mounted in suitable bearings and driven by any suitablepower. R (.lesignatcs a pivoted standard carrying a pivot pin R at itsupper end to which the cam-actuated lever it is pivotally connected.Said lever it has pivotally mounted thereon an anti-friction wheel itadapted to travel upon the circum- The other end of the lever R isforked and carries pivotal screws 1', one in each arm of the fork, whichscrews 1' are mounted in apertures in the shell J S designates a ratchetwheel which is mounted upon the screw J and is adapted, as anintermittent movement is imparted to said Wheel, to cause the screw tomove in one direction or the other amordingly as the wheel is moved inone direction or the other.

Pivotally mounted upon a pin T carried by the standard T is an anglelever T, one end of which is pivotally connected to a pawl T'" adaptedto ride upon the teeth of the ratchet wheel S. The other arm of thelever 's pivotally connected to the lever it by means of the link T. Aspring \V is fixed at its lower end and its upper end is fastened to thelever R and is provided for the purpose of returning the lever it to itsnormal position after having been raised by the plunger.

The under surface of the gear wheel S has teeth S projecting therefromwhich are in mesh with a pinion wheel S mounted upon a stub shaft, and Sis a handle fixed to said stub shaft whereby the pinion wheel S may berotated and return the screw to its lowest position after having beenraised to its highest position.

The operation of my apparatus is as fol lows. The rollers D beingoperated by any source of power, are caused to feed the strands of yarntoward the bobbin, and the rotary movement of the pulleys E, which aredriven by belted connections with a driving shaft, will cause thestrands of yarn to be twisted and cam-actuated means for imparting an inthe same longitudinally, as set forth.

by the hook F rotating rapidly with said pulleys and the rotary movementof the shaft i which is driven by the pulley H which is also connectedto any suitable driving shaft, will 8 cause the twisted yarn to windupon the bobbin. In order to cause the twisted yarn to wind uniformlyupon the bobbin, the pulleys E to which the hook F is fastened l aregiven a slight intermittent longitudinal l movement through the mediumof the cam driven mechanism which causes, at each revolution of the cam,the lever R to tilt, the plunger to be raised, the shaft N rocked and xthe angle lever fixed thereto to impart a slight movement to the shellK. After the lever R has been raised to its highest limit and a furtherrotary movement of the cam R, the lever B will be drawn down by means ofthe spring WV, to its normal position. It will thus be noted that by thecontinuous rotary movement of the cam carrying shaft, the screw will begradually fed upward and the hook moved toward the free end of thebobbin. As the twisting apparatus rotates at a higher rate of speed thanthe bobbin, it will be noted that the strands of yarn will be thoroughlytwisted before being wound upon the bobbin.

What I claim is 1. A twisting and spinning apparatus comprising arotatable shaft, a bobbin fixed thereto, a hollow shaft mounted to movelongitudinally upon said bobbin carrying shaft, a shell swive ed to saidhollow shaft, a flier,

intermittent longitudinal movement to said flier, as set forth.
